I have some snow white Fox tail I am trying to dye into a lime green chartreuse. Some vinegar, hot water, and a dash of salt... The fur will pick up the yellow spectrum but not the green when using the chartreuse. Tried a bunch of different ways varying temp and concentration. I picked up some kelly green to overdye it to give it the green hue but no such luck. I degreased the fur and it was snow white to begin with. Any ideas on how I can get it to pick up the greenish spectrum?
